Press Release

INDIANAPOLIS, Aug 17, 2010 /PRNewswire via COMTEX/ --

Simon Property Group, Inc. (NYSE: SPG) today announced the results of the previously announced cash tender offer made by Simon Property Group, L.P. (the "Operating Partnership"), to purchase for cash any and all of the three outstanding series of notes listed in the table below (the "Notes"). The tender offer expired yesterday at 5:00 p.m., New York City time.

The total principal amount of Notes tendered and accepted for purchase was approximately $1.328 billion, with a weighted average remaining duration of 3.5 years and a weighted average coupon of 6.06%. A charge to earnings of approximately $185 million is expected to be recorded in the third quarter of 2010 in connection with this transaction.

The Operating Partnership will fund the purchase of the Notes with cash on hand and the proceeds from the sale of $900.0 million aggregate principal amount of its 4.375% senior notes due 2021 in an underwritten public offering that closed on August 16, 2010.

"We are very pleased with the results of these transactions," said David Simon, Chairman and Chief Executive Officer. "The aggregate result of the tender offer, combined with the sale of unsecured notes, was an extension of the duration of our senior notes portfolio to 7.5 years and a decrease in the weighted average interest rate of our bond portfolio."
